San Jose, Calif. - Five major IC companies including Applied Micro Circuits Corporation (AMCC),IBM, Infineon Technologies, Texas Instruments and Xilinx announced earlier this month (October) that they hoped to develop and promote a Unified 10Gbits/s Physical-Layer Initiative (UXPi), a program of the IEEE-ISTO. The goal of UXPi is to promote a common 10Gbits/s physical-layer standard across multiple markets, to simplify and accelerate the implementation of next generation 10Gbits/s systems.
A common physical standard will allow developers to significantly reduce the costs and risks normally associated with developing next generation systems. The work of UXPi will complement ongoing and upcoming standardization efforts by other industry bodies such as the Optical Internetworking Forum (OIF).
Industry Trend Towards Serial Connectivity
The broad industry trend toward serial connectivity is being driven as a means to reduce system costs, simplify system design, and provide scalability to meet new bandwidth requirements. Today, standard bodies are defining 3.125Gbits/s and 5-6Gbits/s, and 10Gbits/s serial standards. As these bodies begin to solidify 10Gbits/s communication standards, the need for a unified, compatible physical layer is critical. A common standard will address challenges such as more severe attenuation and signal interference, which arise as 10Gbits/s digital signaling enters the RF domain. And just as important, will ensure interoperability across multiple markets and products.
UXPi hopes to lay the groundwork for common 10Gbits/s standard by solidifying the physical/electrical layer of the 10Gbits/s chip-to-chip and backplane interface - participating in, supporting, and supplementing the efforts of standards bodies, which are often more focused on their respective markets and on defining the upper, logical/digital layers of the 10Gbits/s standards. The efforts of UXPi will enable standards bodies to focus on developing the protocols necessary to serve the unique needs of their respective markets, rather than focusing on the lower layers defining and testing a 10Gbits/s physical standard.
UXPi is organized as a program under the IEEE-ISTO, which provides a legal and administrative platform on which UXPi operations can progress. UXPi plans to work with numerous contributing and adopting companies to develop, refine and make the specification available. Additional information about UXPi membership, its activities and progress is available at www.uxpi.org.
